Anonymous source of unreferenceable news, anonymous none? You really shouldn't make up those stories. They aren't believable and they have no references for anyone to check validity. Check with the Dallas, Tx FCC office, they can verify it. And here is another, get some 6 year old to read it and explaine to you so you will understand. **** HAM RADIO AND PACEMAKERS This is from Angela, VE7ANG’s Newsletter. Richard/VE7SRB has had a pacemaker installed recently. At first he thought he might not be able to continue Ham Radio, but after some research he came up with the following. Perhaps it will be of interest to others. We have researched the literature concerning the effects of amateur radio broadcasts and their potential effects on implanted pulse generators. Most articles concerning the effects of electromagnetic interference (EMI) on pulse generators touch very briefly on the effects of radio frequencies. We have done testing on types of interference most likely to be encountered by pacemakers patients. One category of interference we tested was radio frequency. This covers the HF and VHF bands from 1 MHz to 200 Mhz. Amateur radio, broadcast AM and FM, TV two way communications, short-wave diathermy and CB radios are in this range. Many transmitters have large power capability. Radio amateurs are allowed a one kilowatt input in eight bands, commercial short-wave goes to 250 KW, broadcast to 50 KW, two way radio in emergency short-wave regularly uses 150 watts in mobile installations. Implantable pulse generators may be affected depending on the details of shielding and filtering in the device and modulation of interference signal. Testing was performed on 106 pacemakers comprising 20 different models from various manufacturers. Testing was conducted at interference frequencies of 3.4, 7, 14, 21 and 28.6 Mhz. No effects on pacemaker operation were observed in the presence of field strengths less than 200 volts/meter. Field strengths of this magnitude are unlikely except in the immediate vicinity of a high power transmitting antenna. Overall, our testing indicates that pacemaker patients are very unlikely to encounter problems with radio frequency fields. Certainly we would recommend avoiding direct contact with transmitting antenna. ******* Now go ask the nurse for another blood pressure pill lennyboy so you don't have a stroke. |
